Rock outcrops and other landforms around Yellowstone National Park provide records of three cycles of explosive volcanism that occurred over the past 2.1 million years. Although no magmatic ...

Both isotopes of helium share one bizarre property: superfluidity. Below 4.2 K, helium-4 becomes a liquid but then at 2.17 K it is a superfluid, allowing it to flow without losing kinetic energy. This ...

Helium Isotopes Point To New Sources Of Geothermal Energy. ScienceDaily . Retrieved June 4, 2025 from www.sciencedaily.com / releases / 2007 / 11 / 071129183725.htm ...

Helium is the second most abundant element in the Universe, ... "We identified neon isotope tracers which show a strong association between helium and groundwater," says Danabalan.

A rare isotope of helium gas is leaking from the Earth's core, which suggests the planet formed inside a solar nebula, according to a study published Monday in AGU Geochemistry, Geophysics ...

Natural helium occurs as two isotopes, helium-4 (4He) and helium-3 (3He.) Typically, helium-4 is more abundant in Earth’s crust, whereas helium-3 is more abundant in the mantle below.

Getting physical with the climate crisis. The inferred increase in atmospheric 3 He also greatly exceeds estimates of anthropogenic emissions from natural gas, nuclear weapons and nuclear power ...

Earth's core appears to be leaking primordial helium from the Big Bang, with around 4.4 pounds escaping from the planet's interior every year.. Helium-3 is a light, stable isotope of helium. It is ...

The shortage of helium-3 – a stable isotope of helium important for applications ranging from energy production to medical research – was first identified in the US toward the middle of 2008.

A Rare Helium Surge Unlike Anything Seen Before. The NASA/ESA Solar Orbiter captured the historic surge of ³He, a rare isotope of helium typically found at a ratio of just 1 per 2,500 compared to ...

AFTER the discovery by Urey of the isotope of hydrogen of mass 2 (deuterium) and its concentration by electrolysis, it was natural to examine whether any other stable isotopes of hydrogen, and ...
